SPECFICATION forming part of Letters Patent N o. 487,368, dated December 6, 1892.

Application filed March 23, 1891. Serial No. 386,174. (No model.)

To all wiz/0m t may concern,.-

Be it known that I, FREDERICK KORUPKAT, a citizen of the United States, residing at Glenwood Springs, in the county of Garfield and State of Colorado, have invented a new and useful Method of Fastening a Horseshoe to the Hoof of a Horse or a Mule, of which the following is a specilication.

Myinvention relates to improvements in the mode of fastening the shoe to the hoof by means of fasteners hinged to the shoe at the point of the toe of the shoeand screwed to the side of the shoe through the thickened part of the rim of the shoe. l attain these objects by the devices shown in the accompanying drawings, in which- Figure l is a top plan view, partly in section, of the shoe, showing one of the fastening-arms in position. Fig. 2 is a view in side elevation of one of the fasteningarms- Fig. 3 is a similar View from the opposite side. Fig. 4 is a central longitudinal sectional View of the shoe on the line .e a of Fig. l. Fig. 5 is a side elevation of the same. Fig. Gis a sectional View on the line y y of Fig. l. Fig. 7 is a detail sectional view on the line so, Fig. l. Fig. 8 is a bottom plan View of the hoof, showing the fastening-arm in position on the hoof. Fig. 9 is a View, partly in section, showing the shoe applied to a hoof.

The fastenerf, with the teeth t t, is hinged by lugsl Z to point of shoe and screwed to side of rim r by screw c, which passesthrough the burr s of the .fastenerf and the thicken ed part b of the rim r. Each fastener is brought into place by slipping the lugs ZZ into their respective apertures at the point of the shoe and by sliding the fastener over the rounded part of the shoe, (shown in Fig. 7,) thence by moving the burr s into the conical depression CZ, thence by pressing the burr s against the thickened part b of the rim r, which latter movement is guided by the wart 0, which fits the burr s tightly to the thickened part b of the rim r. The drawing of the screw c through the burr s and the thickened part b of the rim r terminates the process of fastening of shoe to hoof. The sole of the hoof has, however, to be prepared for the attachment of fasteners and shoe by cutting a part of the sole of the hoof between the frog of the hoof and a line 7c lo shown on the bottom of the sole in Fig. S.

The shoe is [irst heated for the preliminary iitting to the hoof, and by means of the groove g a mark or line lo 7c, Fig. S, is made on the sole and serves as a guide for the proper cutting of the portion between the frog and said line k 7a. After this portion has been removed a depending flange or projection is formed. Vhen the fastenerfis brought into position, the teeth t t are pressed into the projection of the hoof, and the combined action of the rim r, the lugs l, the teeth t t, and the screw c secures the shoe firmly to the hooi", and by the growth of the latter the teeth become still more embedded and the rim r tits still tighter to the outside of the hoof.

I am not aware that prior to my invention acombination of rim ou horseshoe, the cutting of part of the hoof for the insertion of a toothed fastener with lugs and burr, screw and wart, and the groove in the shoe, as described, has been used or invented or patented.

NVhatl do claim as my invention, and desire to secure by Letters Patent, is-

l. A horseshoe having a groove adapted to receive a depending flange of the hoot', the front wall of said groove being formed by a rim or flange corresponding to the contour of the hoof, the rear wall being formed by removably-pivoted fastening-arms, said. arms provided with engaging devices for taking into the ange of the hoof, whereby said fiange may be securely clamped between said rim and fastening-arms, substantially as described.

2. In a horseshoe, a groove g, formed between an inwardly-projecting rim and looselypivoted fastening-arms, for the reception of a depending flange cut on the hoof, said fastening-arms being provided with teeth or equivalents for taking into the flange of the hoof and also provided at one end with depending lugs (preferably conical in form) designed to be removably pivoted in corresponding recesses formed in a lug of the shoe and at or near the other end with thickened portions having threaded apertures adapted to coincide with similar threaded apertured portions of the shoe, the screws for connecting the ends of said fastening arms and the shoe, whereby said shoe may be securely clamped in position to a depending iiange of the hoof, and the marking-groove g, substantially as described.

The combination, with a horseshoe, of the ICO fastening devices, substantially as described, and the correspondingiy-forrned reeesses T2,

comprising the curved arms provided with wherein said studs are removably secured, as

hoof-engaging projectionsnthe lugs s, formed and for the purpose set forth.

integral with said curved arms, the lugs b of I the shoe, the coincident threaded apertures i Witnesses:
